the unit from a home automation controller or a computer running special software
Unpacking
Carefully remove the RT-1080, the remote
control, and accessories from the shipping
carton. Save the shipping carton and all enclosed packing material for future use. Shipping or moving the unit in anything other than
the original packing material may result in severe damage.
Keep the original sales receipt. It is your best
record of the date of purchase, in the event
warranty service is ever required.
Placement
Like all audio components that handle low-level
signals, the RT-1080 can be affected by its
environment. Avoid placing the RT-1080 on
top of other components.
6
The RT-1080 generates some heat as part of
its normal operation. There should be 10 cm
(4 inches) of clearance around the chassis,
and reasonable airflow through the installation location, to prevent overheating.
Place the unit on a solid shelf. We recommend
installing the RT-1080 in furniture designed to
house audio components. Such furniture is designed to reduce or suppress vibration which
can adversely affect sound quality. Ask your
authorized Rotel dealer about component furniture and proper installation.
The RT-1080 is supplied with an RR-T92 remote control and must be placed where the
infrared signal from the remote can reach the
front panel Remote Sensor.
Remote Control Batteries
Two UM-4/AAA size batteries (supplied) must
be installed before the remote control can be
used. To install the batteries, remove the cover
on the back of the RR-AT92. Install the batteries as shown in the illustration in the battery
well. Test the control for proper operation, then
replace the cover. When the batteries become
weak the remote control won’t operate the
RT-1080 consistently. Installing fresh batteries
should eliminate the problem.
NOTE:
Remove the batteries from the remote
if it will not be used for a long period of time.
Do not leave run down batteries in the remote control; they can leak corrosive chemicals which will damage the unit.
Cables
Keep power cords, digital cables, and audio
cables away from each other. This will minimize the chance of the audio signal cables
picking up noise or interference from the power
cords or digital cables. Using high quality,
shielded cables will also help to prevent noise
or interference. If you have any questions see
your authorized Rotel dealer for advice about
the best cable to use with your system.
Remote Control
The RT-1080 includes an RR-T92 remote control that operates many of the features of the
RT-1080.
Remote Sensor
The remote sensor receives infrared signals
from the remote control. Do not cover or block
the sensor. It must be unobstructed or the remote control will not work properly.
The operation of the remote sensor can also
be affected if exposed to bright sunlight or
certain types of lighting (such as halogen lights)
that emit infrared light. In addition remote control functions may not work reliably if the batteries in the RR-AT92 are weak.
NOTE:
To use the remote, aim it at the remote
sensor on the front panel of the RT-1080.
Rear Panel Connections
The RT-1080 provides rear panel connections
for audio line level output, two FM antennas,
an AM antenna, computer interface, a remote
IR connection, 12V trigger connections for remote turn-on and AC power input.
NOTE:
Do not plug any system component into
an AC source until system hookup is complete and you are sure that all connections
have been properly made.
RCA Outputs
A pair of line level RCA audio outputs sends
a fixed-level stereo signal from the RT-1080
to your preamplifier, surround processor, or
integrated amplifier. Use a standard RCA audio cable to connect the left output jack to the
left channel tuner input on your system controller and the right output jack to the right channel tuner input on your system controller.
AM Loop Antenna
The RT-1080 includes a loop antenna to receive AM radio signals. Remove this antenna
from the box and locate it near the RT-1080.
Connect the 300 ohm twin-conductor wire from
the loop antenna to the pair of screw terminals labeled AM LOOP, attaching one wire
to each terminal. It does not matter which wire
attaches to which terminal, but make sure that
the connections are solid and that the two wires
do not touch.
English
7
You may need to rotate or otherwise reorient
the antenna to find the best position.
NOTE:
To use an outdoor antenna, connect its
300 ohm twin-conductor wire instead of the
loop antenna, only after a professional contractor has installed the antenna system in
accordance with local electrical codes.
FM Antenna
The RT-1080 has two FM antenna connections,
labeled A and B. This permits you to switch
between two different FM antenna systems
using a front panel or remote control switch.
This feature could be useful to switch between
an indoor antenna and an outdoor antenna
system or between a standard FM antenna and
a cable or satellite TV decoder that provides
an FM antenna signal.
NOTE: The following instructions assume the
use of a standard FM wire antenna supplied
with the unit. To hook up a cable or satellite
TV FM antenna system, see the instructions
supplied with that unit.
The RT-1080 is supplied with a T-shaped indoor FM antenna. Connect the attached coax
F-type plug to one of the FM antenna connectors on the RT-1080. For best reception, unfold the T-shaped antenna. Eyelets at both ends
of the T allow tacking the antenna to a wall,
if desired. Experiment with positioning for best
reception.
NOTE:
To use an outdoor antenna, connect its
75 ohm coax lead wire to the FM connector
instead of the indoor wire antenna, only after a professional contractor has installed the
antenna system in accordance with local electrical codes. In the USA, you will need to use
the supplied F-type converter to connect the
75 ohm coax cable to the antenna input.
AC Input
Your RT-1080 is configured at the factory for
the proper AC line voltage in the country where
you purchased it (115 volts/60Hz in the USA
and 230 volts/50Hz in Europe). The AC line
configuration is noted on a decal on the back
of your unit. Make sure that your unit is configured properly for your AC voltage.
Plug the supplied cord into the AC input receptacle on the back of the unit. Once all other
rear panel connections are completed, plug
the power cord into an AC wall outlet or
switched AC outlet on another component.
12V TRIGGER Connections
The RT-1080 can be activated by a 12 volt
trigger signal from a Rotel preamplifier.
These two connections provide an input to
receive the 12 volt trigger signal from the
preamp and an output to pass through the trigger signal to another component such as a
Rotel power amplifier.
The trigger input accepts any control signal
(AC or DC) ranging from 3 volts to 30 volts.
When a cable is connected to the input and
a trigger signal is present, the tuner is activated.
When the trigger signal is interrupted, the tuner
goes into standby mode. The front panel indicator light remains lit, but the display goes
dark and the unit will not operate.
NOTE:
When using the 12V Trigger feature,
leave the POWER button in the ON position.
EXT REM. IN Jack
This 3.5mm jack receives command codes from
industry-standard infrared receivers (Xantech,
etc.) via hard-wired connections. This feature
could prove useful when the unit is installed
in a cabinet and the front panel sensor is
blocked. Consult your authorized Rotel dealer
for information on external repeaters and the
wiring of a jack to fit the receptacle.
Basic Operating Controls
The following explanations will help you get
familiar with the features and controls. When
a function is available on both the front panel
and the remote, a number (see front panel
illustration) and a letter (see remote control
illustration) are shown in the instructions. For
example, to change from the AM to FM band,
you can either press the front panel button
or use the button
on the remote. When only
one identifier appears, that control is available only on the front panel or the remote, but
not both.
Power Button
The POWER button is located on the front panel
of the RT-1080 and is not duplicated on the
remote control.
Push the button in to turn the unit on. The LED
above the switch and the display will light up.
Push the button again (returning it to the out
position), to turn the unit off.
NOTE: If you are using a switched outlet on
another component to power the RT-1080 or
if you are using the 12 volt trigger feature,
leave the POWER switch in the ON position.
Front Panel Display
The fluorescent display in the center of the
RT-1080 provides status information used in
operating the AM/FM receiver (such as station frequency display, band, preset memory,
RDS information, etc.).
COMPUTER I/O Interface
DIMMER Button
The unit can be operated from a home automation controller or a computer running audio system control software from third-party
developers. This control is accomplished by
sending the operating codes normally sent by
the RR-T92 remote over a hard-wired network
connection from the computer.
Available only on the remote control, this button
selects three display brightness settings: NORMAL, DIM, or OFF. When the display is OFF,
pressing any button or control will return it to
the NORMAL mode. Press the button to cycle
through the three settings.
The COMPUTER I/O input provides the necessary connection on the back panel. It accepts standard RJ-45 8-pin modular plugs, such
as those commonly used in 10-BaseT UTP
Ethernet cabling.
For information on the connections, software,
and operating codes for computer control,
contact your authorized Rotel dealer.
NOTE:
When the tuner is turned off and back
on, the display reverts to its normal setting.

RDS broadcasting has been widely available
in many European markets for years. There
are a large number of RDS stations and most
users will be familiar with the features and
operation. In the USA, implementation of the
RBDS system is more recent. Fewer stations
are broadcasting RBDS signals and the features may be less familiar to many users. Ask
your authorized Rotel dealer for information
on RDS or RBDS broadcasting in your area.
NOTE:
The RDS and RBDS features are entirely dependent on the broadcaster sending
properly encoded signals. Thus, they will only
be available where RDS or RBDS is currently
implemented and where stations are broadcasting these data signals. If there are no RDS
or RBDS stations, the RT-1080 will function
as a standard radio receiver.
NOTE:
RDS and RBDS services are only available on FM broadcasts. The features described are only operational in FM mode.

The Rotel RT-1080 is equipped with RDS (Radio Data Systems) capabilities for Europe and
RBDS (Radio Broadcast Data Service) capabilities for the United States. These broadcast
systems provide additional functionality to FM
radio reception by transmitting encoded information along with the radio signal. This signal is decoded by an RDS or RBDS receiver
and can provide a range of informational
features including:
There are five display options when the tuned
station is broadcasting RDS data and the RDS
indicator in the display is lit. Press the DISPLAY
button to step through the five available options:
1. Standard FREQUENCY display.
2. PROGRAM SERVICE name. This is typically
the station’s call letters, such as BBC1. If
the current station is not broadcasting an
RDS signal, the display will show a blinking PS indication.

3. PROGRAM TYPE. This is a description of
the station’s content from a list of program
types (for example: NEWS, CURRENT AFFAIRS,
INFO, SPORT, EDUCATION, DRAMA, CULTURE, SCIENCE,
VARIED, POP, ROCK, EASY LISTENING, LIGHT CLASSICAL, SERIOUS CLASSICAL, OTHER MUSIC, WEATHER,
FINANCE, CHILDREN, SOCIAL AFFAIRS, RELIGION, PHONE
IN, TRAVEL, LEISURE, JAZZ, COUNTRY, NATIONAL MUSIC,
OLDIES, FOLK, and DOCUMENTARY). If the station
is not broadcasting an RDS signal, the display will show a blinking PT indication.
4. CLOCK TIME. A time and date display
broadcast by the station. If the station is
not broadcasting an RDS signal, the display will show a blinking CT indication.
5. RADIO TEXT. Scrolling text messages broadcast by the station. If the station is not broadcasting an RDS signal, the display will show
a blinking RT indication.
PTY Button
The PTY search function scans for RDS stations
broadcasting a particular type of program.
1. Press the PTY button. The current RDS program content type appears in the display.
2. If desired, change to a different PROGRAM
TYPE using the DOWN/UP buttons to scroll
through the list.
3. Press the PTY button a second time within
5 seconds. The tuner will attempt to find
an RDS station broadcasting the selected
type of program. If the button is not pressed
within 5 seconds after selecting a program
type, the PTY function will be cancelled.
4. If no station is located for the desired content type, the tuner will return to the last
previously tuned station.
5. Cancel the PTY function by pressing any
button (except DIMMER or FM MONO).
TP Button
Searches for an RDS station broadcasting traffic
information programming:
1. Press the TP button. The tuner will attempt
to find an RDS station broadcasting the
traffic programming.
2. If no station is located, the tuner will return
to the last previously tuned station.
3. Cancel the TP function by pressing any
button (except DIMMER or FM MONO).

TA Button
Searches for an RDS station broadcasting
special traffic announcements:
1. Press the TA button. The tuner will attempt
to find an RDS station broadcasting traffic announcements.
2. If no station is located, the tuner will return to the last previously tuned station.
3. Cancel the TA function by pressing any
button (except DIMMER or FM MONO).
AF Button
In some cases, an RDS station is part of a
network of stations broadcasting the same
programming (for example, BBC1 programming in the UK may be available at several
different frequencies). Stations broadcasting
this programming may transmit an RDS data
signal providing the tuner with a list of alternate frequencies where this programming is
available. If this data list is transmitted, an AF
indicator will appear in the display.
The AF button is used to scan the alternate
frequencies to find a stronger signal. The button
is only functional when the AF indicator is lit.
1. Press the AF button. The tuner will scan each
of the alternate frequencies for the same
programming in the stored list and tune to
the strongest signal.
2. If no station is located, the tuner will return
to the last previously tuned station.
3. If the signal strength of the new station is
weaker, the tuner will revert to the previously tuned station.
4. Cancel the AF function by pressing any
button (except DIMMER or FM MONO).
Additional Tuning Features
The following buttons provide features which
may be used to improve FM reception and/
or provide additional functionality:
FM MONO Button
The FM MONO button changes the FM mode
from stereo reception to mono reception. In
stereo mode, a stereo signal will be heard if
the station is broadcasting a stereo signal and
there is sufficient signal strength. A stereo in-
dicator will light in the display. In mono mode,
a mono signal will be heard even if the station is broadcasting a stereo signal.
NOTE: Switching to mono mode can be a useful way to improve the reception of weak or
distant FM signals. Less signal strength is required for clean mono reception than for stereo reception.
ANT ATT Button
Sometimes known as a LOCAL/DISTANCE
switch, the ANT ATT button reduces the signal level at the FM antenna input. For the best
reception of stations located some distance
away, this button should be in the default or
OFF position. However, if you are located in
an urban area very close to the radio transmitter, the incoming signal may be high enough
to overload the FM inputs. Press this button to
reduce the incoming signal. When activated,
a LOC indicator appears in the display. Press
the button again to toggle back to normal operation. This switch only effects FM reception.
FM IF NARROW Button
FM reception works by receiving and decoding a carrier signal centered at the tuned frequency. To accommodate broadcast stations
that may be misadjusted off this carrier frequency, the receiver accepts signals slightly
to either side of the tuned frequency. This
generally provides satisfactory performance.
If you are located in an urban area with a large
number of stations at closely spaced frequencies, you may occasionally notice interference
from adjacent stations. To provide better performance under these conditions, the RT-1080
allows you to reduce the range of frequencies
to either side of the precise tuned frequency,
thus reducing inter-station interference. Press
the FM IF NARROW button to use this feature.
A NARROW indication will appear in the
display. Press the button again to toggle back
to normal operation.
ANT A/B Button
As described in the REAR PANEL CONNECTIONS section of this manual, the RT-1080 provides two FM antenna connections, labeled
A and B. This button toggles between the two
antenna inputs. An A or B indicator will appear in the display, indicating which FM antenna input is active.
